IMPROVEMENT IN sane-mouse.

"r0, ALL WHOM IT MAY OONOERNQ Be it known that I, MATTHEW FLINN, of fit. Louis, in the annuity of St. Louis, and State of Missouri, have made certain new and useful Improvements in Ganglloughs; and I dohercby declare that the following is a full and clear description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon. i

This invention relates, firstly, to an improved construction of the parts which allows both of the wheels to run on the land, instead of having one of them run in the furrow, as most gang-ploughs now do secondly the invention'relates to an arrangement of the draught-connections of the ploughs, whereby the draught is thrown down upon the axle, instead of making these-id connections in a right lino, between the ploughs and the animals drawing it, thereby saving in the traction-power required; thirdly, the, invention relates to an improved device for raising the ploughs up out of the ground.

To enable those skilled in the 'art to make and use my improved 'ploughs, I will proceed to describe'their construction and'operation..

Figure 1, of the drawings, is a side elevation of the improved plough.

Figure 2 is a plan of the same.

Figure 3 is a detail view., I

The wheels A are so arranged upon'the axle B, and theploughs C are attached to the said axle in such a manner, as to enable the wheels to run on the unploughed ground, instead of having one wheel to run in the furrow, as is usually the case with gang-ploughs. fig. 2, the draught of the machine is made much lighter than in the machines formerly constructed.

The second feature of this invention consists in attaching the plo ughs C to the axle B, by means of the.

sliding blocks 0, connecting-rods a, and sectors 0 Theme arms of the sector a? are pivoted to the beam B, at agwhile one end of the sector-rail is linked to the axle at 9;, and the other end of it is attached to the connecting-rod e, by ineans of a knuckle-joint at 21 The blocks 0 are dove-tailed into the face plates 0 which are attached to the bottom of the plough-post C. The blocks a being allowed to move forward and backward in their hearings in the plates 0 the draught of the ploughs is made independent of the posts C, which said posts are only used for the purpose of affording thenecessary lateral support to the ploughs, The sectors, c, being constructed and arranged as before described, the force which is transmitted through them to the ploughs, will be divided into the forces indicated by the arrows y, y, and y The force 3 is drawing down from the axle, while the force g is lifting up on the beam B, which transmits the strain thus; thrown upon it back to the axle, which is thus made to sustain a large portion of the weight of the machine while in'o'p eration, andthe lifting force y serves .to assist the operator in raising the ploughs out of the ground. The forces exerted in the direction of the arrows 3 are those acting really as traction forces,' to draw the plough's forward.

The third feature of this invention relates to the device for raising the ploughs out of the ground. This device consists of one or more cogged sectors, D, and a cogged pinion, cZ, gearing intothe same. Thefron't ends of the sectors are sustained on the axle B, while the iear ends of them are carried on the caster-wheel A. The pinion (Z is placed upon a shaft having its bearings in the frame or beams 13, and is. actuated by a crank, ll'z As the driver sits upon the seat S, he can easily turn the crank 65 so as to cause the pinion d to roll up in the rack or sector D, and as the axle of the said pinion is fixed to the said beams B, they, and the ploughs (l, which are attached thereto, will be raised thereby, the traction force expended in the direction of the arrow 1 acting to assist in the raising operation. A hook, (Z attached to the side of one of the beams B will catch in a notch in the side of the sector D, when the ploughs are up, and serve to hold them up when not in use. )A foot-lever, (1", attached to the side of the beam 13, is connected with the hook (Z by. means of a rod or link, in such a manner-that the, operator, by pressing his foot thereon when required, can withdraw the hook from the notch in the sector, and allow the ploughs to fall as required. When coulters are required, they may be attached to the connecting-rods c.

By means of this improved arrangement, which is shown in Having described my invention, what I claim, is-- I 1. I claim the sliding blocks 0, connecting-rods c, zmii'sectors c", when arranged and employed, substantiaily as herein shown and described, for the pnrposc'of transmitting the draught from the 12410 to the ploughs. 2. I claim the sectors or sector D, pinion (Z, and beams B, when combined and nrranged as heroin shown and described.

3. I claim the hook (i and lever 02", when combined with the bezim B, and sector D, as described and shown.

I MATTHEW FLINN.
